Floristic and structure of the tree layer of urban homegardens of the municipality of Belterra, Pará

Abstract

Floristic composition and structure studies increase the knowledge of ecological and botanical information and provide subsidies for the management and conservation of biodiversity in agroecosystems. Therefore, the objective of this work was to evaluate the floristic and tree vegetation structure of urban homegardens in the municipality of Belterra, Pará. Nineteen homegardens were sampled, in which all tree individuals with a diameter at breast height greater than or equal to five centimeters (DBH ≥ 5cm) were inventoried. A total of 503 trees were registered, distributed in 39 species and 18 botanical families. The most important species in the structure of homegardens evaluated were Theobroma grandiflorum (372 individuals), Hevea brasiliensis (36) and Persea americana (28). Despite being located in urban areas, the evaluated homegardens are diversified and have great importance for the food supply of Amazonian families.
